COMBINATION PADLOCK.

Application filed June 11, 1926 Serial No. 115,386.

-My invention relates to certain improvements in combination padlocks. ,g My invention can be applied to either a lock having a longitudinally movable swivel shackle, or to a lock having a shackle provided with a series of notches arranged to be engaged by a bolt.

One object of the invention is to so con struct the lock that it can not be jarred to release the bolt. 7

Another object is to provide means for preventing the withdrawal of the shackle from the lock.

And a further object is to provide means for lockingjthe bolt when the {dog is moved clear of the notches in the tumblers.

My invention further relates'to the arrangement of the spring which acts to throw the bolt and apply tension to the tumblers;

and still further relates to improvements in the click mechanismior the knob ofthelock.

Fig. 13 is a perspective view of the casing for the long arm of the shackle;

Fig. 14; is a viewof the bottom plate;

invention; and y Fig. 16 is a view showing a long shackle lock made in accordance with my invention. 1 is the casing of the lock, which is eye lindrical in the present instance and consists of a back plate. 2 and an integral deep flange 3, which is rolled over as at 4 upon the cover plate 5, the cover plate having a lug 6 which enters a recess 7 portion.

8 is the knob of the lock having a pointer 9, and the shank of this knob extends through the cap. plate 5 and is attached to a notched disk 10, which forms a part of the click mechanism. The disk 10 has pin 11 which is arranged to enter a slot in the body 13 in a tumbler -12 of the lock, and is also i plate 17 which conforms to the shape of the.

casing as clearly shown in Figs.'3 and 14 The plate is held from turning in the casing by a lug 17* which extends into a groove 1 in the casing. Secured to this bottom plate is a spindle 18, which is grooved at one side 19, Fig. 2. Mounted on the s indle are the several tumblers '20, whic are spaced apart by washers2l. These washers have projections which enter the groove 19, so as to prevent the washers turning on the spindle when the tumblers are turned. w

The tumblers 20 have notches 22, and

. the upper tumbler 12 has a notch14 toreof one tumbler strike those of another tumbler, in order ,to bring the notches into proper alignment with the dog.

'25 is a bolt having a slot 26 for a seeuring rivet 27, which holds the'bolt against the plate 17, yet' allowing it to move longi- Fig. 15 is a view of a modification of the tudinally. The plate is slotted at 28 and extending into these slots are the project-ions 29 of the bolt. The bolt has a portion 30 which is arranged to extend into the notch 31 of the arm 32. of the shackle 33. The portion '30 is inclined soas to allow the shackle to be forced into the look when the 7' bolt is projected, the end of the shackle be- 7 ing beveled as at The long arm oi the through a casing 36 riveted to the bottom plate 17. The end of the shackle is reduced to form a shoulder 37 and secured to the casing 36 is a spring 38, which pro vjects into the path or" the shackle, so that 7 when the'shackle is raised to its full extent, as shown by dotted lines in Fig. 4, the spring will engage the shoulder 37 and prevent withdrawal oi: the shackle, but allowing it-to turn freely. Inthe present instance, the spring 38 is held between the casing 36 and the bottom plate 17, the main body of thespring extending through a slot 39 in the casing, while the opposite end of the spring is bent and enters a slot 40in the casing. Thus the spring is held firmly in position.

The dog- 41 is mounted on a pivot pin 42,

8 carried by a bolt-throwing lever 43. This to enter the lock of the casing.

lever has a projection 44 which enters a' notch 45 in the bolt, 25,.so that when the lever is moved to an unlocking position, the bolt 25 is withdrawn. The notch 45,

yield when the short arm of the shackle is forced into the lock of the casing.

I Mounted'on the spindle l8 is a spring 46,

which has one or more coils and has arms 47 and 48. The arm 47 rests against the casing 36, while the arm 48 rests against the bolt, as clearly shown in Fig. 2. The coiled portion of the spring acts to yieldingly hold the tumblers up against the main tumbler of the lock, so that while the tumblers can be turned through the medium of the knob 8, they will retain their position on the spindle.

In place of the coil spring just described, two springs may be used. A coil'spring 46 may be located on'the spindle and'act to frictionally hold the tumblers in position, and a separate spring 48 may be secured to an extension of the casing 36 and bear against a projection 2 5 on the bolt, so as to yieldingly hold thebolt in the projected position, which is clearly shown in Fig. 15 of the drawings. j 1

A dog 41, whichis mounted on a pin 42, is pressed against the tumblers by a spring .49 which is mounted on the pin 42, one arm bearing against the projecting portion of the dog, and the other arm .bearing against a lug 50on the lever 43.

Bent from the bottom plate 17 is a stop 51, which is engaged by the portion 52 of the dogwhen the dog is out of the notch.

shackle extends 7 position, and, second, as a This prevents the movement of the bolt when the bolt is'in a locked position. This stop also prevents the withdrawal of the dog from the notches when the locking lever 43 is turned, as this movement brings the dog directly in front of the stop 51. U

The operation is as tollowsz wh'en the mechanism is in a locking position, the knob Sis turned,'using the proper combination, until all of the notches in the tumblersare in line with the dog, when the latter will be forced by its spring 49 into the notches. Then, on continuing to turn the knob in the proper direction, the lever 43 will withdraw the bolt from engagement with the nose of the shackle and release the latter, which can be moved longitudinally, and when the nose of the shackle is clear of the casing, the shackle can be turned, the spring-stop 38 limiting. the withdrawal of the long arm of the shackle. hen the mechanism is to be moved into locking position, the shackle is forced into the lock and engaged by the bolt. The disk which isattached to the knob forces the dog out of engagement with the tumblers. knob'the tumblers are distributed and the lock is in a locked position, and when in this position the dog is turned, so that the bolt cannot be forcibly withdrawn. 7

On the cover plate 5 is a dial having a On continuing to move the v series of numerals thereon as shown in Fig.

1. The rivet 16 for the click spring extends through the cover plate and has a projecting head preferably located at the mark 60 of the dial. This head of the rivet acts as sage of the shackle. The bolt can engage any oneof a seriesof notches in the shackle, and the spring 38 acts as a stop to prevent the insertion of the shackle in the reverse direction.
